At least one person -- Amber Rose, West's ex -- seems to suggest the fling was for real. During a live Tuesday appearance on The Wendy Williams Show, the famously bald/close-cropped model, 29, played it extremely coy when asked about the alleged Kim/Kanye hookup.

Rose was much more direct talking about her own dalliance with Reggie Bush, Kardashian's very serious NFL beau of two years. She shot down talk that she and the Miami Dolphins running back, 26, were the cause of his final March 2010 split with Kardashian.

"We were both going through a hard time. We were each other's rebounds. It was brief, it was nice, he was a great guy!"

But these days, it's all about another rapper -- Wiz Khalifa -- for the stunning model. "I want to be with him for the rest of my life," she gushed, noting that they're not married or engaged yet. "I never did [believe in marriage] until I met him. I never thought it would happen for me!"
